Earthquake, Earthquakes

I regularly get concerned messages from friends and family back home whenever Vanuatu gets another earthquake. I find it a little humurous that vanuatu so regularly experiences such strong earth quakes and i never feel any of them on my island, but in the span of the week i have been in Vila i have felt 4 earth quakes and not received a single worried message haha. I have no idea of how strong the earth quakes are though, but its always kind fun feeling everything shake!
